Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

TIMING CHARACTERISTICS FOR HIGH-SPEED MODE (C
B
= 400pF, Note 13)
Note 1:
All WLP devices are 100% production tested at T
A
= +25°C. Specifications over temperature limits are guaranteed by
design and characterization.
Note 2:
For DC accuracy, the MAX11612/MAX11614/MAX11616 are tested at V
DD
= 5V and the
MAX11613/MAX11615/MAX11617are tested at V
DD
= 3V. All devices are configured for unipolar, single-ended inputs.
Note 3:
Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range and
offsets have been calibrated.
Note 4:
Offset nulled.
Note 5:
Conversion time is defined as the number of clock cycles needed for conversion multiplied by the clock period. Conversion
time does not include acquisition time. SCL is the conversion clock in the external clock mode.
Note 6:
A filter on the SDA and SCL inputs suppresses noise spikes and delays the sampling instant.
Note 7:
The absolute input-voltage range for the analog inputs (AIN0–AIN11) is from GND to V
DD
.
Note 8:
When the internal reference is configured to be available at AIN_/REF (SEL[2:1] = 11), decouple AIN_/REF to GND with a
0.1µF capacitor and a 2kΩ series resistor (see the
Typical Operating Circuit).
Note 9:
ADC performance is limited by the converter’s noise floor, typically 300µV
